Siemens Servo Motor Repair

Do you have a Siemens servo that has suddenly stopped working? Is there a loud noise that started and you can’t get it to stop? Send it to Repair Zone “the servo experts” for a free evaluation.

We can quickly tell you why it stopped working through our thorough electrical and mechanical testing procedures during our evaluation to pin-point the issue or issues.
We use:
• Surge testing
• Megger
• And Back EMF testing
• Along with mechanical tolerance checks and
• Torque testing of any brake if present • We also verify the feedback device on the motor to see if it is operating correctly

These tests will tell us where we need to go during the repair. During a standard repair, we wash and bake the stator and rotor to remove all contaminates, bearings are replaced with high performance bearings, new seals are installed, and any broken connector is replaced. If the stator is shorted, we rewind it in-house using Nano-coated wire for longevity. If the end bells or shaft need to be machined, we do it here in our machining center.

Your Siemens motor is then re-assembled, the encoder or feedback is aligned, and we connect it to the appropriate Siemens test fixture and run test at various speeds, in both directions, stopping and starting several times for 2 hours or more. When you receive your Siemens servo motor back from Repair Zone, it looks and runs like new again. A 1 year warranty ensures your satisfaction is our priority.
